Hello
To send data to the server at once, use uid as the only value in the row.
However If there is a column whose column type is a drop-down list, the uid of the row changes when it is modified.
So after the modification, the number of lines increases to two.
In particular, I wonder if there is any way uid does not change without using the id attribute of source,
The scenario is as follows
1) Click the Add Row button
2) Double-click the added row to change to edit mode and click outside the grid
3) The number of lines increases to two
Here is code to test
